27mm Front Sway Bar:

The 27mm front sway bar is significantly stiffer than the factory bar, dramatically reducing body roll during cornering. The increased stiffness helps keep the Miata flat through corners, improving tire contact patch and overall grip. The front bar works in conjunction with the rear bar to create a balanced, neutral handling characteristic.

15mm 3-Way Adjustable Rear Sway Bar:

The 15mm rear sway bar features 3-way adjustability, allowing you to fine-tune the Miata's handling balance. The three settings allow you to adjust the rear bar's stiffness to dial in the perfect amount of oversteer or understeer for your driving style and tire setup. This adjustability makes the kit versatile for street driving, autocross, or track use.

Reduced Body Roll and Improved Balance:

By increasing sway bar stiffness front and rear, the Eibach Anti-Roll-Kit dramatically reduces body roll during cornering. This keeps the Miata flatter through corners, improving tire contact patch, grip, and overall cornering speed. The balanced front/rear setup maintains the Miata's neutral handling characteristics while significantly improving performance.

Direct Bolt-On Fitment:

The Eibach Anti-Roll-Kit is engineered specifically for the NB Miata chassis, providing direct bolt-on fitment using factory mounting points. No cutting, drilling, or modifications are required. The kit includes all necessary hardware, bushings, and end links for a complete installation.

3-Way Adjustability - Tuning Guide:

• Softest Setting: More oversteer, playful handling, ideal for wet conditions
• Middle Setting: Balanced handling, recommended starting point
• Stiffest Setting: More understeer, stable handling, ideal for high-grip tires

Start with the middle setting and adjust based on your preference and tire setup.
